Yep exactly. Two units and a shitstorm of wiring.

I left the wiring in, just unplugged the boxes

 

A shit storm is an understatement hahaha

Going to temp fix just now (in the morning when I can see what I'm doing) and do a full removal when I can be bothered.

Cheers mate.

 

UPDATE!

The car was hooked up to OBD - 3 keys showing as registered to ECU - Immobiliser checked out fine.

The old H&P Alarm unit is out, after much swearing and removing of insulation tape etc...

Original wiring restored to factory layout.

The original problem remains.

Key in, turned to II - Pump primes, key flashes continually, car turns over but does not start at all.

Has anyone any clues?? I'm at wits end!!

Edit: Does anyone know whether the S2000 transponder halo is the same as the one used in any other models of honda? I could try and get another from a salvage yard to try it?

 

Basic Q's. Spark plugs? Battery's negative lead ground? Other electrical connection points under the hood? Just to rule-out simple things first.


Good luck!

 

I can now confirm it was a cooked immo problem.

I no longer have a problem

Thanks to all here who have helped/ suggested things- it's much appreciated!! (By both my boss and I!) /

I now have an extra chunk of knowledge about my car, so all in its a good day
